Old Stuff — Cosmology and Astroparticles

Here you can find some older stuff I did during my time at Bielefeld University. My main research circled around the question “What was the content of the first three minutes of our universe? And how can we describe it?” My PhD was awarded with a fellowship of the Friedrich-Ebert-Foundation. I was further an associated  fellow of the international graduate school GRK 881: “Quantum Fields and Strongly Interacting Matter” in the Cosmology and Astroparticle Physics group

The “New Scientist” wrote an article about my work on the cosmic QCD transition: “Big bang, part 2: the second inflation”.

“phys.org” featured a story about my work on neutrino asymmetry and the cosmic micrwave background: “Observations of early universe hint at a giant excess of anti-neutrinos”.

The “New Journal of Physics” published a video of me and Dominik Schwarz in which we introduce our article about lepton asymmetry and the CMB: Video

My Publications on arXiv and SPIRES.

Some of my older presentations from the web:

• “The first second of lepton asymmetries (PDF)” TAUP2011, Munich, Germany.
• “Lepton Asymmetries and the cosmic QCD transition (PDF)“, PASCOS2009 meeting in Hamburg,Germany.
• “Lepton Asymmetries and the Cosmic Trajectory in the QCD Phase Diagram (PDF)”  “Phases of Strongly Interacting Matter” 2009 in Paris, France.
